Excellent, I am not surprised it raised interest among Audio Coding people :
you clearly demonstrated your point that SA can be used as a universal and
evolutive coding technique.
As you say, a general-purpose language such as C or Java might be considered
as having the same capabilities, but there is no doubt saol is more suitable
for sound algorithms description.
I have no doubt this remarkable paper will boost SA hardware and software development.
